Hibernia Line operates a direct, year-round ferry service between Ringaskiddy in Cork, Ireland, and Boulogne-sur-Mer in northern France, connecting passengers and freight with mainland Europe without UK transit. The route offers regular sailings, generally Monday to Saturday, including overnight crossings, and serves both private travellers and commercial freight customers. Passengers can travel with cars, campervans, caravans and motorbikes, or as foot passengers, making the service suitable for holidays, road trips and onward European journeys. Pet-friendly cabins are available for travellers bringing their animals.

On board, guests can choose private inside or outside cabins and use lounges, WiFi and other seating areas. Dining facilities offer freshly prepared meals and lighter options, with bar service; menus are being developed with chef and brand ambassador Rachel Allen, featuring Irish ingredients and European flavours. Hibernia Line also provides freight booking and customer support, alongside passenger travel information and booking services. From Boulogne-sur-Mer, travellers can continue towards Paris, the Opal Coast, Belgium, the Netherlands and Germany, while Cork provides access to routes across Ireland.
